Elranatamab, sold under the brand name Elrexfio, is a medication used for the treatment of multiple myeloma.[1][4][5][6] Elranatamab is a bispecific B-cell maturation antigen (BCMA)-directed CD3 T-cell engager.[1][4] Elranatamab is administered subcutaneously.[1][4]
The most common side effects include cytokine release syndrome, fatigue, injection site reaction, diarrhea, upper respiratory tract infection, musculoskeletal pain, pneumonia, decreased appetite, rash, cough, nausea, and pyrexia (fever).[4]
Elranatamab was approved for medical use in the United States in August 2023,[1][4][7] and in the European Union in December 2023.[3]
Elranatamab is indicated for the treatment of adults with relapsed or refractory multiple myeloma who have received at least four prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody.[1][4]
The most common adverse reactions include cytokine release syndrome, fatigue, injection site reaction, diarrhea, upper respiratory tract infection, musculoskeletal pain, pneumonia, decreased appetite, rash, cough, nausea, and pyrexia.[4]
The US Food and Drug Administration (FDA) prescribing information for elranatamab has a boxed warning for life-threatening or fatal cytokine release syndrome and neurologic toxicity, including immune effector cell-associated neurotoxicity.[4]
The safety and effectiveness of elranatamab was evaluated in MagnetisMM-3 (NCT04649359), an open-label, single-arm, multi-center study that included participants with relapsed/refractory multiple myeloma who are refractory to at least one proteasome inhibitor, one immunomodulatory drug, and one anti-CD38 antibody.[4] Overall, the study consisted of 97 participants naïve to prior BCMA-directed therapy and who had previously received at least four prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody.[4]
The FDA granted the application for elranatamab priority review, breakthrough therapy, and orphan drug designations;[4] and granted approval of Elrexfio to Pfizer Inc.[4]
In October 2023, the Committee for Medicinal Products for Human Use of the European Medicines Agency adopted a positive opinion, recommending the granting of a conditional marketing authorization for the medicinal product Elrexfio, intended for the treatment of multiple myeloma.[8] The applicant for this medicinal product is Pfizer Europe MA EEIG.[8]
Elranatamab was approved for medical use in the United States in August 2023,[1][4] and in the European Union in December 2023.[3]
